Title: Coin operated vending machine
IPC: G07F9/10
Filed: 1938-02-23
Abstract: 512,027. Coin-freed article-delivery apparatus. BRUS, G. J. Feb. 23, 1938, No. 5776. [Class 27] In a coin-freed machine for vending ice-cream packages and the like, the packages 7 are contained in magazines 6, Fig. 2, removably placed in a cooling box 1 at the top of the machine, the box 1 being insulated from the machine casing 3 by packing 2 and supported in position by wooden battens 4. The box 1 is made of good conducting material such as copper plate and has a separate compartment 5 containing liquid of low freezing point cooled by an electric motor-driven refrigerator located in the bottom of the casing 3; After the insertion of a coin, the bottom package of a selected compartment 6 is withdrawn by pulling a draw-bar 8. In the machine illustrated there are four compartments with four draw-bars, and a single coin-releasing mechanism. Each draw-bar 8, Fig. 3, has an insulating plate 9 to cover the delivery opening in the box 1, and a U-shaped package carrier 10 engaging the lowest package in the magazine 6 and provided with a shelf 11 which supports the pile when the lowest package is withdrawn. The portions 10, 11 are made of copper and the shelf 11 may have an extension which contacts with the bottom of the box 1 so that the carrier also is cooled. The lowest package drops down a shoot 39 to a tray 36 hinged at 37 inside a fixed delivery tray 40. The tray 36 is rocked against the action of a spring 38 and by a link 35 withdraws a rod 33 out of the path of a pin 32 on a door 30 which is hinged at 31 and can now be pushed inwardly by the purchaser to obtain access to the package in the tray 36, 40. The forked ends 45 of levers 44 are pressed against the plates 9 of draw - bars 8 by a spring 46, so that when a draw-bar is pulled out, a lever 44 is moved and obstructs the pin 32 on the corresponding door 30. This prevents the door from being opened until the draw-bar 8 is returned to its initial position and so the passage of warm air to the cooling box 1. A draining tube 48 is provided for the tray 40. Coin action, with stationary coin forming abutment. In the absence of a coin, the bars 8 are prevented from being pulled out by pivoted latches 15, Fig. 4, pressed by springs 17 to engage notches 16 in the bars after a small initial movement. The ends of the latches engage notches 18 in a rectilinearly movable lath 14, the springs 17 moving this lath against the action of a spring 21. One end 22 of the lath presses a pin 23 through an aperture in a coin shoot 24. If a coin 25 is inserted, this coin prevents movement of the pin 23 and the lath 14 so that the latches 15 are prevented from moving into locking engagement with the drawbars 8. Known interlocking mechanism, comprising suitable pieces 26, 27, Fig. 3, which are wedged apart by a rod 8, prevent more than one rod 8 from being actuated at a time. According to the Provisional Specification, the lath for controlling the locking latches is rotatable and has an arm which bears against the inserted coin to prevent such rotation.

Abstract: 582,757. Resonators ; wave guides; thermionic tubes. BRITISH THOMSONHOUSTON CO., Ltd. April 16, 1943, No. 6159. Convention date, April 16, 1942. [Classes 39 (i) and 40 (v)] The wave reflected from the junction of two pieces of wave guide or coaxial line of different characteristics is balanced out by the wave-reflected from an additional irregularity provided in the neighbourhood. For example, in a wave guide of rectangular section, Fig. 5, in which the portion 13 is filled with water, slabs 11, 12 of quartz are provided so dimensioned and spaced in accordance with principles discussed mathematically in the Specification that the resultant reflection to the left of the slab 11 of a wave transmitted from left to right is zero. Similar slabs may be provided in the neighbourhood of the junction of two pieces of guide of different diameters. In the arrangement shown in Fig. 8, the reflection due to a glass plug 39 sealing a splitanode magnetron oscillator is neutralized by appropriately dimensioned and spaced slabs 41, 42. Similar slabs 53, 54, Fig. 10, may be provided to neutralize reflection at the junction of a coaxial line with an antenna or other unshielded portion 51<1>. An an alternative to these dielectric slabs, the central conductor may have enlarged portions or the diameter of the outer conductor may be effectively reduced by means of conducting rings 73, 74, Fig. 12. More than two slabs may be provided. In another arrangement, Fig. 7 (not shown), not forming part of the invention, reflection is annulled by means of a single slab of dielectric material of a suitable thickness and suitably spaced from the place at which the main reflections occur.
